We explore light-driven manipulation, levitation, and propulsion of ultralight weight macroscopic objects (size >> ) whose properties are tailored by nanophotonic design. Our analysis expands the regime of self-stabilizing optical manipulation from the regime of microscopic (i.e., wavelength-scale) objects such as nanoparticles to the macroscopic regime of many m, mm, cm, or even meter-scale objects, which can be achieved by tailoring the radiation pressure forces by controlling the anisotropy and spatial distribution of light scattering along the object surface. From this has emerged a general, scale-independent theory for the light-induced manipulation of macroscopic objects with patterned nanoscale components that impart optical anisotropy. From the theory, we can develop specific examples, including a scalable design that features silicon resonators on a silica substrate where these nanophotonic structures serve to self-stabilize the body dynamics.
